In the U.S. Senate race, 50 percent support Booker while 22 percent back Republican Steve Lonegan.

“Booker and Christie go into the fall with numbers that can only make them smile,” said Krista Jenkins, director of PublicMind and professor of political science at Fairleigh Dickinson University. “The hopeful sign for their opponents is the double digit numbers of people who remain ‘unsure’ about whom they intend to support in either election. For many, their preferences have not yet hardened.”
